Phys. Rev. Lett. 87, 043001 (2001) [4 pages]Microwave Ionization of an Atomic Electron Wave PacketReceived 22 December 2000; published 5 July 2001 A short microwave pulse is used to ionize a lithium Rydberg wave packet launched from the core at a well-defined phase of the field. We observe a strong dependence on the relative phase between the motion of the wave packet and the oscillations of the field. This phase dependent ionization is also studied as a function of the relative frequency. Our experimental observations are in good qualitative agreement with a one-dimensional classical model of wave packet ionization. © 2001 The American Physical Society URL:
